PRELIMINARY
3.6.2
V
CC
, V
PP
AND RP# TRANSITIONS
The CUI latches commands as issued by
system
software and is not altered by V
PP
or CE#
transitions or WSM actions. Its default state upon
power-up, after exit from reset mode or after V
CC
transitions above V
LKO
(Lockout voltage), is read
array mode.
After any program or block erase operation is
complete (even after V
PP
transitions down to
V
PPLK
), the CUI must be reset to read array mode
via the Read Array command if access to the flash
memory array is desired.
3.7
Power Supply Decoupling
Flash memory’s power switching characteristics
require
careful
device
designers should consider three supply current
issues:
decoupling.
System
1.
2.
3.
Standby current levels (I
CCS
)
Read current levels (I
CCR
)
Transient peaks produced by falling and rising
edges of CE#.
Transient current magnitudes depend on the device
outputs’ capacitive and inductive loading. Two-line
control and proper decoupling capacitor selection
will suppress these transient voltage peaks. Each
flash device should have a 0.1 μF ceramic
capacitor connected between each V
CC
and GND,
and between its V
PP
and GND. These high-
frequency, inherently low-inductance capacitors
should be placed as close as possible to the
package leads.
